Cardiac CT in the context of value-based care

Area of Science:

• Cardiovascular Imaging
• Radiology
• Health Economics

Background:

• Cardiac computed tomography (CCT) is frequently equated with coronary CT angiography (CCTA) and coronary artery calcium scoring (CACS).
• CCT also encompasses CT applications for structural, valvular, and congenital heart disease, and other cardiovascular pathologies.
• The current clinical landscape shows the most established value and evidence for CCT in coronary artery disease (CAD) assessment.

Purpose of the Study:

• To examine the role of cardiac CT within the framework of value-based healthcare.
• To predominantly focus on CCT's established value in assessing coronary artery disease (CAD).
• To highlight critical questions regarding the definition of quality healthcare using CCT.

Main Methods:

• Review of existing clinical evidence and health economic data for cardiac CT.
• Focus on studies demonstrating value and clinical utility, particularly for CAD.
• Commentary on the broader applications of CCT beyond coronary assessment.

Main Results:

• Cardiac CT, particularly CCTA and CACS, demonstrates significant clinical utility and value-based evidence in the assessment of coronary artery disease (CAD).
• The evidence base for the value of CCT in non-coronary cardiovascular conditions is still developing and less robust compared to CAD.
• Defining quality healthcare metrics for CCT necessitates further critical evaluation.

Conclusions:

• Cardiac CT provides demonstrable value in the diagnosis and management of coronary artery disease (CAD).
• Further research is needed to establish the health economic and value-based evidence for non-coronary cardiovascular applications of CCT.
• Optimizing CCT use within value-based care models requires a clear understanding of its evidence across different cardiovascular pathologies.
